    I'm doing a proof of concept application for my department in an attempt to get the Telerik grid into our company. However, I'm running into an odd issue. Essentially, there seems to be a disconnect between where my mouse cursor is and where the header I'm trying to drop is. I'm attaching an image as it's kind of difficult to explain.

    Any help would be appreciated as this is a major feature that we need.

    Hello Alan,

    Could you please share with us if there any modification on zoom level or any specifics in your scenario since we are unable to get this problem under normal circumstances. Is it possible to post code snippet/project that demonstrates this issue?

    Best wishes,

    I have a sample project ready to upload, just not sure exactly where I should upload it. If I submit a ticket, will it (or does it need to) be linked to this post?

    Hi, I get some weird bug when dragging a gridview header.

    Whether I drag the header to use it with the grouping, or drag it to rearrange the columns, the header being dragged gets an offset of (I'm estimating) 250.

    Attached is a screenshot of what I mean.
    The mouse is just above "GUI" in the screenshot, and the dragged header is way out of the picture.

    Why is this happening, and more importantly, how can I fix this?

    Hello Ruan,

    Can you please paste the XAML of the Page where RadGridView is placed. I believe this would be helpful in  our attempts to reproduce the issue here.

    Thank you so much for responding Pavel, below is the xaml:


    <telerik:RadGridView x:Name="AssetRegister" ItemsSource="{Binding AssetCollection}" 
                                     AutoGenerateColumns="True"
    HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
    HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch"
    Grid.Row="1" AutoGeneratingColumn="AssetCollection_AutoGeneratingColumn"/>


    Thant's it. No templates or styles.
    (I had styles and templates initially, but removed them as soon as i realized that there's a bug. First I thought that one of my styles are breaking it, but I still have this bug)

    Hi Ruan,

    Thanks for providing the XAML . I was hoping to see some fancy containers or render transforms to blame but no luck :) .

    So the next thing to check would be - are you running the application in non default screen DPI settings ?
    If this is the case you may try setting the DragAndDropManager.ExecutionMode property to "Legacy" .

    Let me know in case  this does not solve the issue.

    Hi Pavel

    I've confirmed that we are using normal (default) dpi settings throughout the app.

    I have not been able to solve this problem, an apologize for not being able to give more information
    (I really don't understand what's causing this.)

    I deleted the grid, all templates and styles (they weren't being used, but was in the usercontrol resources) but the problem persists
